Question

Quizplus · Accepted Answer

In the Customers table, the customer number is the primary key. It is not likely to be a foreign key in any other table since it uniquely identifies each customer in the system. A foreign key is used to link two tables together, and it references the primary key of another table. Therefore, options A, C, and D are more likely to have the customer number as a foreign key as they involve linking other tables with Customers.
